erank ll for operating the driver through the intermediarv of pitnien15. 16 being the (21111 shaft. whieh may be journ'aled in the frame h orother suitable part ot' the inaehine. as usual.

As the wire is advaneed through the anvil l) whieh is provided as usualwith slot 17 for the reeepliion ot' the wire. it is pushed bark into itsseat by a wire guide shown in detail in Fig. 5. and eonsisting of an arm1h supported by pivot 19 and having an int-lined l'aee :0. arranged tobe engaged by the tip of the wire as it is advaneed through the slot ofthe anvil, the wire guide being of the usual or any suitableeonstruetioin and held up to its work by spring 2t. or ol her suitablemeans. The wire being properly plaeed in the slot of the anvil. it isthen engaged bv the bifureated wire former It). the end of the wirehaving been previousl severed. and both extremities of the severedportion are thus bent do\\'nwardl into a substantially U shape by theformer. whieh straddles the anvil and is provided with groove in theinner fares of its branehes. as usual. for guiding the driver 11. whiehit enibraee and also engaging and holding the wire while being formedand driven. As the driver 11 desrends in the net of engaging and drivingthe staple. it first engages with the inrlined top fa e of the :uni] fas usual. and l'orees the same longitlulinall v out of it path andeventuallv engages and drives the staple tlo\\'ti \'attll whilethibranehes ol' the staple are supported again t inward. ending ineoiiperation with the grooved branehe ot' the former. by the sup porterl'l. \vhieh 'is also engaged by the driver 11 and foreed baeluvardlv outof the way as the staple proeeeds downwardlv. the staple supporting endof the supporter 1; provided with a eurved tare '3 hr initiating in apoint it. whieh is the last portion of the supporter to withdraw fromthe enibraee of the staple and the lower fat-eol' the supporter isstruek on a suitable are 25.

so that as the supporter swings biu-lvwardly out of the way of thedriver the point it will he brought into elose propinouitv to thesurface into whirh the staple is being driven. its the driver rises fromthe driven staple the supporter 1:2 is returned to its former positionby any suitable means sueh a a pring or other elastir' element 2o. whilethe anvil f is replaeed by the spring 27.

, which, together with the spring 26. serves to keep the end of theanvil and the curved surface 23 of the supporter 12 in close relationduring the staple forming and driving operations. In this example of theinven tion the. anvil 9. shown in connection therewith. is of a familiartype, arranged in a horizontal position in a suitable socket 23,containing also the spring 27. the anvil being held against rotaryaction by a guide pin 29 in the usual way. An anvil of any othersuitable form. however. may be employed.

The staple supporter 12 is connected by means of a pivot 30 to the lowerend of a hanger 31, which serves to sustain the supporter in position.According to this invention, the hanger 31 is composed of asubstantially straight rod or block provided at one end with a pair oflugs 32. by means of which the hanger is given support upon the former10. which is provided with shoulders 33 for the purpose.-sucl1 shouldersbeing formed by recesses 34 in the sides of the former, which areextended in an upward direction to permit of a limited range ofmoveIm-nt of the former independently of the hanger 31, so that whilethe supporter 12 is resting contiguous to the surface into which thestaple is being driven, the former may continue its downward movement inthe act of forming the staple over the anvil. The bar 31, which rnayconveniently be rectangular, in cross section. is slidably housed in acap 35, in the lower end of which is a recess 36 for accommodating thesupporter 12, so that when thecap 35 is removed the lugs 32 may hesimply disengaged from their recesses 34, and the supporter and itshanger 31 removed from their guide way in the cap 35, the same beingheld therein preferably without any other attachingmeans. The cap 35may, of course, be held in place by screws 37, or other suitabledevices. The hanger 31 also constitutes a housing for the supporterspring 26. To that end the hanger is provided with a socket 38, whichmay be conveniently formed by a drill, for receiving the spring, andalso a plunger 39 which may be of cylindrical form, with its lower endprotruding from the socket of the hanger and pro-. vided with suitablebearing point -10, shown in this example of the invention ashemispherical. engaging the supporter 12. which has a rounded face 41,upon which the bearing point 40 rests, and by which the supporter 12 isheld up to its work, contiguous to the anvil 9 under the influence ofthe spring 26. The plunger 39 is held against accidental discharge fromits socket 38 by a pin 42, engaging in a groove 43 in the plunger.

The former 10, containing the driver 11,

is housed within a guide box 44, suitably supported on the frame member8, and provided with a passage or groove -15 for receiving and guidingthe. former. Both the exterior sides of the former and the'guide wallsof the groove 45 are preferably parallel. both transversely andlongitudinally. so that the former together with the driver may be.removed transversely from the frontof the box 44 when the cap 35 1sremoved.

The outer edge or face of the former is flush with the face of the box44, as better Shown in Figs. 6-7. and the hanger 31 whose rear face isstraight and fiat, fits against the outer face of the former 10.111111is thereby held against undue inward movement, while it is held againstoutward movement as'well as lateral movement by the cap 35. which latteralso overlaps the outer fa e of the former for preventing the latterfrom mov ing outwardly.

The wire guide 13 is also preferably mounted in a recess 46 in one sideof the cap 35, containing also the wire guide spring 21, so arrangedthat the wire guide may recede into the recess 4tl entirely out of theway of the former and driver when they descend. Thus it will be seenthat when thecap 35 is detached the former and driver may be readilyremoved from their guide box 44. the pitmen 15 being first disconnected.and the supporter 12 and its hanger 31 may be as readily removed fromthe cap 35 with the supporter spring 26 and plunger-39 intact. It willalso be seen that by thus arranging the supporter spring within thehanger bar 31. or in position contiguous to and substantially parallelwith the driver and former. certain protruding parts heretofore employedin front of the machine for supporting the spring are dispensedwith.leaving'the front of the machine free and unob The combination withstaple forming [f and driving members, of a block cooperating with andlocated adiacent thereto. a support pivoted to said block. and a springactuated plunger mounted Within said block parallel to one of thevertical faces thereof and arranged to operate against 'said support toforce the same into the path of movement of the staple forming anddriving members at predetermined intervals.

3. The combination with staple formingand driving members, of a blockcooperating with and located adjacent thereto, a support pivoted to saidblock, a spring-actuated plunger mounted within said blockand arrangedto operate against said support and force the same into the path ofmovement of the staple forming and driving members at predeterminedintervals, and means for limiting the movement of said plunger.

at. The combination with a frame, of a staple former and driver mountedtherein, a cap secured to said frame provided with a projection having alongitudinal passage therein, said passage having a transverseenlargement at the lower terminal thereof, a hanger mounted forreciprocation in said passage, means for reciprocating said hanger fromthe former aforesaid, a staple sup porter pivotally connected to thelower end of said hanger and mounted within the enlargement aforesaidand contained wholly within the cap, and means mounted within saidhanger for forcing said supporter into the path of the staple former andthe driver at predetermined intervals.

5. The combination with a staple former, elongated recesses formed oneach side of said former, a block located adjacent to said former, lugscarried by the upper terminal of said block adapted to be received insaid recesses whereby the former may have a movement independently ofsaid block, a staple support pivoted at the lower end of said block, andautomatic means contained entirely within said block whereby said staplesupport is caused to swing into the by said former, and having a passagein the lower terminal thereof, a spring-pressed plunger mounted in saidpassage, and a staple supporter mounted on the lower terminal of saidhanger, said staple supporter being segmental in formation and extendinginto the enlargement aforesaid, the portion thereof in saidenlargen'ient being ope 'ated upon by the spring-pressed plunger.

7. The combination with a block, of a quadrental support pivoted at thelower terminal thereof, said support having the convergent faces thereofcurved inwardly, a plunger mounted in said block, a spring mounted insaid block, and a plunger acted upon by said spring and bearing againstone of the curved edges of said support and adapted to force the latterautomatically in a given direction at predetermined intervals.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, on this 3rd day of August, A. D.1911.
